Application filed July 2, 19310. serial No. 670,135.

To all whom it may concern:

Be it known that I,.W.-.I1rr.n L. Mann, a citizen of the United States of America, residing at Flint, in the county of Geucsec 5 and State of Michigan, have invented cor-- tain new and useful Improvements in Bah ance steeringsPla-nes for Aeroplanes, of which the following is a specification, reterence being bad therein to the amompany ing drawings.

In. the manipulation of aeroplanes it is desirable to raise or lower either end of the frame independently and it is also important to be "able to swing one end of the law chine on the other as a pivot.

This invention relates to a balance and a steeringplane for aeroplaneaand to an it!" range'ment thereof whereby the machine may-beraised or depressed bodily or at either and independently, and whereby the operator may swing the machine if desired.

Th invention consists in the matters hereinafter set forth," and more particularly pointed out in .the appended claims.

25. In the drawin s, Figure 1 is a view of the main planes an frame worlc of an aeroplane provided with balance and steering planes that embodies features i of the in vention; Fig. 2 is a plan View of the balance so and the steerin plane; and Fig. 3 is a plan view of a modihcation thereof.

As shown herein, one or'more main planes l'of anaeroplaneare secured to thelaterally extending framework 2 of the machine by whichthey are sustained in parallel relation at a fixed inclination to the line of flight by suitable struts. A pair of balance and steering planes are secured near the extremities of t 40 'a rudder member 3 is pivoted at its forward margin to a member 4 of the frame to swing in planes that are substantially vertical to the mainplanes. A balance member 5.is pivot-ally secured at its forward end to a rod .6 or like part secured at right angles to the member-4 that serves as an axis for the rudder plane 3. A segmental aperture indicated at 7 in the balance plane permits the oscillationof the rudder-member. Snitabl y disposed flexible. connections 8 running toward the operators station permit the manipulation of the rudder members and other flexible connections 9. are used to give the required angle of inclination to the balance.

planes.

As herein shown the frame work of the 'muin planes with a pair of steering planes eimain planes. As herein indicated machine is made u of open panels and the forward margin 0 each balance plime may extend only a portion of the width of a panel as indicated in Fig. 2 or it. may span so the entircpanel as shown in Fig. 3. In either construction the operator by proper manipulatioii of the steering members may swingthe machine on one end as on a pivot, even if the main rudder of the machlneis an out of order. By simultaneous depression or elevation of the rear edges of the balance planes the machine may be raised or lowered in its flight. If either balance plane is raised or lowered the adjacent portion of the machine is correspondingly depressed or elevated. Furthermore it the machine be swung sharply around in a horizontalplane the outer balance member may be de rcssed to overcome the cfi'cct of inertia whic tends 7a to make that portion of'the machine dip i when swinging around a curve.

While herein shown in combination with a bi-plane it is apparent that the balance and steering planes may be used with a so mono-plane type oi. machine in which instanccthey can be laced above in below the main plane as pre erred.

Obviously, changes in the, details of construction may be made without departing from the spirit of the invention and I do not care to limit myself to any particular form or arrangement of parts.

I claim as my invention:

1. The .-.ombin'ation in an aeroplane, of

syinmctrically disposed between the main planes near the extremities thereof, each being angular-1yadjustable on an axis substantially perpendicular to the main planes, and a pair of lmlunce-plancs'that-are each angularly adjustable on an axis that intersects "a steering plane axis, the steering planes each bcingoscillatory in an opening of a companion balance plane.

2. The combinationin an aeroplane, of a frame, a pair of main planes on the frame in substantially parallel, spaced relation, a pair of steering planes symmetrically.disposed on the frame between the main planes near the extremities of the latter, each angular-1y adjustable on an axis substantially )erpendicular lo the main plane, and alunce planes each angularly adjustable on anaxis that intersects the axis of a'steering plane, thebalance planes having openings in which the steering planes are oscillatory.
